NSTEAM STEERING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 242,634, dated June 7,1881. Application filed September 28, 1880. (No model.)

' To all whom it may concern:

Beit known that we, JAMES FINDLAY GUILD, of Dundee, co unty ofForfar,Scotland, and AR- THUR EDWARD KNIGHTS, of the city, county, and StateofNew York, have invented a new and useful Improvement in Steam SteeringApparatus for Vessels, of which the following is a specification. 1

Our improvements relate to apparatus for steering vessels by steam andother power.

The objects of our invention are to move a vessels rudder easily,quickly, and with perfeet regularity, to have it completely undercontrol and almost silent in its action, thus in a great measureovercoming objections to the usual steam steering apparatus, especiallyon passenger-steamers. The objects are, further, to provide for steeringvessels either by hand or power; to provide for the relief of theoperative mechanism from the injurious effects of shocks by strokes ofwaves against the rudder, and to reduce the power usually required inapparatus of this character.

Our invention consists of the steam-cylinder, the steam-chest havinginlet-ports and containing a' valve, theliquid-cylinders havingpassages, the valve-chamber provided with a partition and valves, andthe pistons connected with thesteering-chains, combined together andprovided with a hand-wheel for giving simultaneous movement to thevalves, and in the combination of the cross-shaft, the steering-wheel,and eccentrics with the steamcylinder, the liquid-cylinders, and theirvalves, for the simultaneous operation of the valves. These featureswill be more particularly described hereinafter with reforence to theaccompanying drawings forming part of this specification, wherein-Figure 1 is a plan. view of steering apparatus embodying ourimprovements. Fig. 2 is a vertical longitudinal section of thesteam-cylinder and valve. Fig. 3 is a horizontal section of oneauxiliary cylinder or regulator. Fig. 4 is a plan view, and Fig. 5 asection, of the differential eccentric. Fig. 6 is a verticalcross-section of the steam and liquid cylinders. Fig. 7 is an end viewof the wheel-standard. Figs. 8 and 9 are sectional front and side .viewsof the regulator-valves.

'Similar letters of reference indicate corresponding parts.

A is the steam-cylinder and B B the liquidcylinders, placed on oppositesides of cylinder A. These cylinders have separate pistons, the rods aof which extend through the heads at both ends, and are connected bycross-heads b. The steering chains or ropes c are connected to heads bby shackles or eyes, and pass around fixed sheaves a and along the deckto the eccentrics G, from which chains or ropes 0 pass around aquadrant, (1, that is fixed on the rudder-post b, the ends of the chainsor ropes'bein g connected to the forearm of the rudder head or shaft,which may be extended to any desired height, as required;

D is the steam-chest containing slide-valve c, and provided withinlet-portsc to the cylinder A and exhaust-port 01. Above thesteamchest, in suitable bearings, is a cross shaft, j, carrying thewheel g, and also carrying eccentrics c, from which rods extend to across-head on the valve-rod f, so that the valve is moved by operationof shaft f. The valve 6 is so formed and placed in relation to the portsthat when it is at the middle position both. ports a are open foradmission of steam and the exhaust closed, thereby giving equal pressureat both sides of the piston-head, while the movement of the valve ineither direction from the center closes the port 0 at that side to steamand opens it to the exhaust, thus relieving the pressure at one side.

The cylinders B are provided with passages 9. Both these cylinders areconnected by a pipe, h, at each end, which connect the passages g. Thepassages g of one cylinder, B,

communicate with a valve-chamber, E, 0011- tainin g valves t, by whichpassage of the fluid is permitted or stopped. At the endsof cylinder Bare screw-taps z", which extend into the openings or ports 9 frompassages g to the interior of thecylinders, so that these openings canbe closed more or less by turning screws 2', and the escape of fluidregulated. As shown in Fig. 6, the rods '6 of valves i are connected toa cross-head, that is, in turn, connected to the rod of an eccentric,r,on shaft f, so that the valves are simultaneously operated with thesteam valve.

The chamber E is divided by a central partition, 7L2, in which is a portfor passage of the liquid from one passage, 9, to the other. The valves43 are fitted at opposite sides of partition If, so that they close theport when in their middle position and open it by movement in eitherdirection. There being two valves,

the pressure comes on them alternately at the back, thus keeping theirfaces pressed over the port.

The cylinders B will be preferably filled with oil. At 70 are reservoirsused for supplying the oil, and in which a supply is maintained to keepthe passages full in case of accidental waste. The ports 9 are placed ashort distance from the ends of cylinders B, so that the piston-headswill be cushioned by the oil. The cylinder A may have spiral springsfitted to prevent undue strain on the heads by the piston throughnegligence.

The outer end of shaft fand wheel g are supported by a standard, 1,which also carries a vertical shaft, L, that will be suitably connectedwith and moved by the rudder, to show by the pointer l carried by shaftZ, the angle of the rudder at all times on a fixed dial, m. The

standard lalso carries a ring-shaped index-- plate, an, and mechanism tomove the same for indicating the travel of the steam-valve. On the wheelg is a pointer, which shows on the plate at the position of the steamand oil valves. The arrangement of the marks is thus: When the pointeron the wheel is at the Word port it indicates that the steam-valve is atthe extreme length of its travel, with the exhaust-port and oil-valveopen to the port end of cylinder A, thus allowing escape of steampressure sufficient for the travel of the piston in that direction. Whenthe pointer is at steady port it indicates that the valve is in positionto entirely close the steam-port and oil-passages, thus entirely lockingthe apparatus at any point in the movement. The same applies in theopposite or starboard direction. When the pointeris at a marl: steady itwill indicate that the oil-ports are open and the steam-valve inthemiddle position, so that steam is admitted equally on both sides ofthe piston-head, with the rudder in the fore and aft or centralposition. The oil-valves & being moved at the same time, the oil passesfrom one side of the piston-heads to the other. To lock the wheel it isonly necessary to return the valve to the central position by turningthe wheel, and the oil-valve being thereby moved to close the oil-portthe rudder is locked. To return the rudder the wheel is to be turned inthe opposite direction and held until the indicator shows the rudder tobe in the position desired.

We do not limit ourselves to the use of a single steam-cylinder nor toany special number or arrangement of regulating-cylinders.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent I 1. In apparatus for steering by steam orother power, the steam-cylinder A. steam-chest D, having ports 0, andcontaining valve 6, liquid-cylimlers B,havingpassagesg, chamber E,provided with partition [L2, and valves tand pistons a, connected withthe steering-chains, combined together and provided with a handwheel forgiving simultaneous movement to the valves, substantially as shown anddescribed. 2. In a steering apparatus for vessels, the combination, withthe steam-cylinder A, the liquid-cylimlers B, and their valves, theshaft), the eccentrics e 0, connected to a cross-head on the valve rodf, the eccentric a", connected to the cross-head, of the valve-rods iand the wheel g, substantially as herein shown and described, ter thesimultaneous operation of the valves.

The above specification of our invention signed by us the 9th day ofAugust, 1880.
